Damian Thompson, the writer of this article and of a blog called Holy Smoke at The Telegraph, is publishing a book called, and about, Counterknowledge. It's basically about conspiracy theories; I'm not sure why he needs a new name for them. He included creationism, so it may be the way they dress themselves up in the rags of science to strut their stuff.
He quotes Michael Shermer, the editor of Skeptic magazine, to this effect. The mistaken belief that a handful of unexplained anomalies can undermine a well-established theory lies at the heart of all conspiratorial thinking, as well as creationism, Holocaust denial and the various crank theories of physics.
Shermer is pointing to the widespread misconception that science 'tells it how it is'. People don't seem to be able to grasp, or accept, that science is, first of all, a method and that its theories are just that: theories, the best ones available to explain the evidence. A scientific theory is never definitive, just as anomalies are only unexplained so far. Science is always a work in progress; the anomaly doesn't necessarily disprove anything.
This is obviously not enough. People need and want conspiracies not least for the comfort that they bring. If the multinationals, the CIA, the Jews are controlling everything, at least someone is - far better that than the chaos which seems the only alternative. In addition, there is the added benefit of an excuse for our own failure - I, or we, can't get ahead because the multinationals, the CIA, the Jews (add for taste) are holding me, or us, back.
It doesn't stop there. Conspiracy theories also single out a clear group of Baddies, just like in the movies. This is the sort of economy of means that the mind always seeks, for the simple reason that it makes the world more comprehensible. As a habit of mind, it is both lazy and a sign of the our (natural) unwillingness to accept the role of chance in all things. It is just unacceptable that often there is no clear answer to the question, why? Conspiracy theories provide it, and, as well, a name to apply to that other great question, who's to blame?
